I have avoided dry cleaning since I was a kid and some good family friends ran a mom and pop dry cleaning business in the 60s.
They were both going deaf in their 40's. The doctor told them why and they added some good exhaust fans for the hanger rack room.
The vapors were de-waxing their ears and scarring their ear drums. I figured I didn't really need this odor in my house.

Local kilt maker Kathy Lare told me her horror story if being put in the hospital from pressing a customers kilt that had been stored with moth balls. She and I go the cedar route for this one.
